ios字体设置

ios中的字体：

字体是图形用户界面显示文本的基础。Cocoa在UIKit框架中为开发者提供了高层次的API以及方便的枚举、加载和使用字体。Cocoa Touch 使用UIFont 类来封装字体。每个ios设备都内置了系统字体。字体被组织成字体族科（Families），每个族科又包含字样（Faces）。例如，Helvetica 是一个字体族科，Helvetica Bold是Helvetica族科中的一个字样。要加载字体，你必须知道字体的字样（字体的名字），要知道字样，你必须知道它的族科。怎么获取系统字体的族科呢，我们可以循环输出系统字体族科，使用UIFont类的familyNames类方法，通过这个类方法得到字体族科名字然后用UIFont类的fontNamesForFamilyName：类方法，传递family name作为参数，并返回一个字体名称的数组（array）:

- (void)enumerateFonts{
for(NSString *familyName in [UIFont familyNames]){
NSLog(@"Font FamilyName = %@",familyName); //*输出字体族科名字

for(NSString *fontName in [UIFont fontNamesForFamilyName:familyName]){
NSLog(@"\t%@",fontName);         //*输出字体族科下字样名字
}
}
}

　　

在ios模拟器上运行代码，得到如下结果：

...
Font Family = Geeza Pro
GeezaPro
GeezaPro-Bold
Font Family = Helvetica Neue
HelveticaNeue-Italic
HelveticaNeue-Bold
HelveticaNeue-BoldItalic
HelveticaNeue

...

字体族科后面加-Bold就是加粗 加-Oblique就是倾斜等
